摘　　要：以夏热冬冷地区某实际地埋管地源热泵系统为分析对象,对夏季采用冷却塔供冷而仅冬季采用地埋管和消防水池联合供热的系统运行参数进行了6a测试。建立了地埋管三维管群模型,通过数值计算方法对地埋管周围岩土的温度分布进行了热平衡分析和计算。通过测试数据与理论计算结果进行对比分析,得到了影响大地自调节能力的影响因素。Based on an actual ground-source heat pump system in hot summer and cold winter area,the system operation parameters were tested for 6 years under the state of using cooling tower for cooling in summer but the ground heat exchanger and fire pool for heating in winter.A three-dimensional（3D） tube-group model was established,and the thermal balance analysis and calculation of the ground temperature distribution around the ground heat exchanger were conducted by the numerical calculation.According to the comparison between the test data and the theoretical results,the influencing factors of the ground adjustment ability were obtained.
